Overview of presentation
  • Introduction and overview
  • IT barriers, accessibility, and legal
    requirements
  • Web Accessibility Standards
  • WAI current and future
  • Section 508
  • Web Accessibility Roadmap

5
Common IT Barriers
  • Software that requires the use of a mouse to
    perform commands is inaccessible to people with
    disabilities that cannot use a mouse.

6
Common electronic equipment barriers
  • A copier that has controls outside of accessible
    reach ranges is inaccessible for some persons who
    use wheelchairs.

7
Internet Barriers
  • Most Internet sites use images to convey
    information.

8
Internet Barriers
  • However, if these images are not labeled, users
    who use screen readers cannot access them.

Go to discovernd.com, the official site for North
Dakota State Government programs and services.
9
Internet Barriers
  • If these images are mislabeled, then users who
    use screen readers cannot understand them.

10
Internet Barriers
  • If these images are flashing at a high rate, they
    can cause seizures in people with photosensitive
    epilepsy.

11
Internet Barriers
  • If the site uses color to portray information,
    people with visual impairments like color
    blindness may not be able to access that
    information.

12
Internet Barriers
  • If the colors used in a site have poor contrast,
    it may be difficult for some users to read.

13
Internet Barriers
If the colors used in a site have poor contrast,
it may be difficult for some users to read.
14
Internet Barriers
  • If the site has multiple navigation links, it may
    be repetitive for users who use the keyboard to
    navigate the site.

15
Legal Requirements for Accessibility
16
Americans with Disabilities Act (ADA)
  •                                                   
              
  •     Prohibits discrimination on the basis of
    disability in employment, programs and services
    provided by state and local governments, goods
    and services provided by private companies, and
    in commercial facilities.

17
Americans with Disabilities Act (ADA)
  •                                                   
           
  • Title II of the ADA requires that programs and
    services offered by state and local government,
    including public educational settings, when
    viewed in their entirety, be accessible to
    individuals with disabilities unless creating a
    such access causes a fundamental alteration or
    undue financial or administrative burden.

18
Americans with Disabilities Act (ADA)
  •                                                   
           
  • Title III of the ADA requires that public
    accommodations make reasonable modifications
    (unless such modifications cause fundamental
    alteration or undue burden) so that individuals
    with disabilities have the opportunity to
    participate on an equal basis or benefit equally
    from their goods, services, and facilities.

19
Americans with Disabilities Act (ADA)
  •                                                   
           
  • The ADA was passed in 1990 and does not
    specifically address access to online resources
    and other electronic and information technology.

20
Americans with Disabilities Act (ADA)
  •                ADA requires effective
    communication. According to the US Department of
    Justice Covered entities under the ADA are
    required to provide effective communication,
    regardless of whether they generally communicate
    through print media, audio media, or computerized
    media such as the Internet. Covered entities that
    use the Internet for communications regarding
    their programs, goods or services must be
    prepared to offer those communications through
    accessible means as well. (Opinion letter dated
    9/9/1996)

21
Section 504 of the Rehabilitation Act
  •                                                   
           
  • Similarly to the ADA, Section 504 does not
    specifically reference or prescribe accessibility
    of Web-based or other information resources, but
    includes requirements that apply to accessibility
    of Electronic and Information Technology (EIT).

22
Section 504 of the Rehabilitation Act
  •                                                   
           
  • 504 requires that educational entities that
    receive federal funding make their programs and
    services accessible to qualified individuals with
    disabilities unless doing so creates a
    fundamental alteration or undue burden.

23
Section 504 of the Rehabilitation Act
  •                                                   
           
  • 504 also requires that educational entities
    provide reasonable accommodations in employment
    for qualified people with disabilities unless
    doing so creates an undue hardship.

24
Section 508 of the Rehabilitation Act
  •                                                   
           
  • Section 508 of the Rehabilitation Act Amendments
    of 1998 requires that when federal departments
    and agencies procure, develop, use, maintain, or
    upgrade EIT they must ensure that it complies
    with the 508 standards developed by the Access
    Board, unless doing so would pose an undue burden
    on the federal department or agency.

25
Section 508 of the Rehabilitation Act
  •                                                   
           
  • Section 508 applies to the federal government.
    Some state governments have adopted the 508
    standards for their websites. There is some
    question about whether or not states receiving
    federal funding are required to comply with
    Section 508.

26
Section 508 of the Rehabilitation Act
  •                              
  •                             
  • Section 508 includes a set of minimum standards
    for web design.

Web Accessibility Roadmap
47
Web Accessibility Roadmap
  • If you dont have a destination, then any road
    will take you there.
  • What is our destination?
  • Our goal is to design websites that are usable by
    every user
  • This is a lofty and difficult to achieve goal

48
Goal Design for everyone
  • People using screen readers
  • People who are deaf or hard of hearing
  • People who cant use a mouse
  • People who are color blind
  • People with differences in attention/perception

49
Goal Design for everyone
  • People using different web browsers
  • People using different screen resolutions
  • People using phone web services
  • People using handheld display units
  • People using car computing systems

52
Recognize that you are never Done
  • This is a dynamic environment
  • New websites
  • New technologies (e.g., distance learning)
  • New users
  • New tools and techniques
  • New standards
  • This is an ongoing process like painting the
    Golden Gate bridge

53
Web Accessibility is Iterative
  • Iteration means A procedure in which a cycle of
    operations is repeated, often to approximate the
    desired result more closely.
  • You cant do everything at one time
  • Think of a spiral, moving out from the center
  • The center is your current situation
  • The end of the spiral is your goal

Roadmap Review
  • Start with Awareness and get the policy-making
    level of the institution involved.
  • Create a Web Accessibility Policy
  • Select a minimum compliance level (e.g., WAI AA)
  • Get a commitment for resources
  • People, equipment, tools, training
  • Create a Web Accessibility Action Plan with
    enforcement procedures

59
Roadmap Review contd.
  • Perform an initial assessment of the
    accessibility of the websites (first spiral)
  • Prioritize the repairs to be made
  • creating accessible Web pages for core
    institutional information such as course work,
    registration, advising, admission, catalogs, and
    student services information. UW-M policy
  • Organize the resources to do the repairs

60
Roadmap Review contd.
  • Execute the repairs and test the results
  • Publish a Progress Report on Web Accessibility
    periodically
  • Repeat the spiral, tracking progress toward
    compliance over time.

61
Remember our goal
  • Our goal is to design websites that are usable by
    every user.
  • If your websites arent accessible, then it is
    time to start making them accessible.
